Pressure Transducer Performance standard to on and off highway engines and vehicle OEMs Rugged for heavy equipment and outdoor use Designed specifically for high volume applications Stainless Steel wetted surfaces Medium to extremely high pressures CE Approval DESCRIPTION The pressure transducer from the Microfused line of MEAS sets a new price performance standard for demanding engine and vehicle, and industrial applications. This transducer is suitable for measurement of liquid or gas pressure, even for difficult media such as contaminated water, steam and corrosive fluids. The transducer pressure cavity is machined from a solid piece of 17-4 PH stainless steel. The standard version includes a 1/4 NPT pipe thread allowing a leak-proof, all metal sealed system. There are no O-rings or organics exposed to the pressure media and the durability is excellent. This automotive grade pressure transducer with stainless steel hermetic pressure ports and integral electrical connector boasts up to 43,000psi (3000Bar). The exceeds the latest industrial CE requirements including surge protection and is overvoltage protected to 16Vdc in both positive and reverse polarity.
